To ail whom it may concern."

Be it known that I, ADQLPHUS SYLvnsrnn DENNIS, a citizen of the UnitedStates, residing at Cleveland, in the county of Cuyahoga and State ofOhio, have invented certain new and useful Improvements in Adding-andRecording Machines; and I do deciare that the following is a full,clear, and exact description of the invention, which will, enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to improvements in adding and recording machines,and particularly to a machine on which i have two several applicationsin the United States Patent Ofiice for Letters Patent, one dated March25, 1898, Serial No. 675,063, and the other having renewal date of March31, 1898, Serial No. 67 6,006.

The present invention therefore consists of certain improvements on theconstructions appearing in said application, all substantially as shownand described, and particularly pointed out in the claims.

. In the accompanying drawings, Figure 1. is a side elevation of thecomplete machine. Fig. 2 is a plan view of the machine. Fig. 3 lincA A,Figs. 2 and 6. Fig. 4 is a longitudinal sectional elevation on line B B,Figs. 2 and 6. Fig. 5 is a central longitudinal sectional elevation online C (J, Figs. 2 and 6. Fig. 6 is a plan view of the machine onsection-line D D, Fig. 4. Fig. 7 is a plan view looking down from line EE, Figs. Land 5. Fig. 8 is a rear elevation of the machine looking tothe left fromline G G, Fig. 4., Fig. 9 is a cross-section on line F F,Fig. 4, looking to the right. Fig. 10 is a front elevation, partlysectional, of the carriage and the pivoted columndetormining leverstherein. Fig. 11 is a cross-sectionof the adding-wheels proper, thetotalizing-wheels and associated parts on a line corresponding to H H,Fig. 12. Fig. 12 is a cross-section of three several adding-wheels,showing their bearings, as hereinafter more fully described. Fig. 13 isa cross-section on line 1 1, Fig. 11, showing the totalizing-wheels ontheir shaft. Fig. 14 is a perspective detail of a singletotaiizingwvheel out of the group in Fig. 1 3. Fig. 15, Sheet t, is anelevation of the type-bar for printing the items. Fig. 16 is across-sectional view of the machine on a line corresponding to L L,Fig.2, but omitting all the mechanism, except that shown for automaticallyshifting and feeding the ribbon. Fig. 17 is a detail sectional view,enlarged, of one of the ribbon-wheels, as hereinafter more fullydescribed. Fig. 18 is a sectional elevation of part of the mechanismshown in Fig. 16 on line J J at the left. Fig. 19 is an elevation online K K, Fig. 16.

In the views thus shown 2 represents the frame of the machine, whichcarries all the other parts directly or indirectly, whether stationaryor operative. The keys are represented by 3, of which there'are ten inthis machine, running from O'to 9, inclusive,

and in addition thereis a space-key 4: to correct errors in the coiurnnwork, as heremafter described. The nine several keys are employed towrite the items, whatever their size,

but have nothing to do with the totalizing mechanism, which is aseparate line, as will be seen farther along.

The carriage 5 rests horizontally across the top central portion of themachine, as seen in plan, Fig. 6, and in elevation, Fig. 5, and carriesa number of parts, as will appearit runs on ball-bearings on thechanneled crossraiis'ti of the main frame and is under constant springtension through the flat springcoil 7, Fig. 7, having one end fastenedto its inclosing case 8 and the other to shaft 9. A,v

drum 10,.rigid on this shaftI and acorrespond-- ing drum 11 on theopposite side of the machine, Fig. 9, are connected by endless metaltape 12, secured to the carriage 5 at one point, so that every time akey-lever is depressed to print a character the carriage is fed forwardone step after the manner of a typewriter.

On the rear end of shaft 9 is a segmental ratchet 13, adapted to beengaged by two escapement-pawls 14 and 15, successively, Fig. 8. Thesepawls are arranged side by side on an upright rocking postl6, which hasa head '1? on which pawi 15 in rigid and pawl la is pivoted. Normallypawl it engages ratchet 13, and when a key is depressed post in isretated and pawl 14- carried inward out of on gagement, while at thesame time pawl .15 takes its place before permitting movement of theratchet 13 and holding shaft 9 still. l deantime pawl 14 has been drawndown by its link connection to engage the next lower tooth, as will soonappear.

All the key-levers have like operations, and when any one is depressedit strikes the cross-- frame iii beneath, Fin". Said frame is pivoted atboth sides on cross-shaft 19, on which the keys are independentlypivoted. Frame 18 has an arm 20, centrally through which the rearvertical pawl-carrying post 16 is rotated by means of rod 21, having" ani..-shaped head 22, and the arm 23 on post 16 havingin this instance aset-screw 2 engaged by head 22 when it is forced inward by arm 20. Thiscauses post 16 to rotate just enough to exchange pawls in engagementwith ratchet 125, as above described, and this occurs every time akey-lever is depressed. 'ihe further action of pawl 14 is dependent onthe movement of the printing hammer supported on arm 26, carried byshaft 27, Figs. 5 and s. The blow of this hammer to make an imprint isdependent on spring-pressed bolt 30, which rests against short arm 31,rigid with shaft 27, said bolt being; confined to opcrate in the casing"32, containing; spring 33, hearing against the head of said bolt.Another short arm 34:, rigid with shaft 27, engages the short portion ofL-shaped head 22, in which is a slot 35, adapted to receive thedownwardlycurved end'of said arm 3 1 when said head is carried rearwardthrough the action of rod 21, and shaft 27 is rotated as the hammer 25delivers its stroke. 'llhen as the kcylever which has caused this actionrises the rod 21 is carried back by the action of its spring 36., theshort arm 3% is raised out oi its slot to position, as in Fig. 5, by thepull from spring 7 on shaft 9 and pawl 14 and its link -11, bolt isforced back under this pull, and hammer 25 assumes normal retired place.

Now reviewing the operation of pawl 1 1, Fig. 8, the said pawl ispivoted in head 17 and is subject to opposite movements. Thus a bolt4:0, supported in arms on the post 16, serves to hold the said pawl upin normal position to engage the teeth on ratchet 1'3; but beingspring-pressed said pawl can be pressed back by the teeth on the ratchetto allow for the rotation of said ratchet and its shaft 9 when thecarriage is set to starting position. it also has a link 11, connectingwith arm 4:). on shaft 27, so that when said .shaft is rotated for theactuation of the hammer it will pull down the pawl 14: for enough toengage in over the next pawl below, as pawl 15 is released by swingingbackward to rest instantiy on releaseolf the key-lever. 'ihen manta aspawl 14 rises to normal position it allows, rotation enough of segment13t0 make a step of feed for the carriage to print in the next column. Abow-spring 14" (shown in Figs. 5, 7, and 51) returns post 16 to normalposition, and then pawl 14 is engaged by a lower tooth on ratchet 13 andis carried up to the limit of its movement by the rotation of theratchet under its own spring-pmver. This spaces the carriage.

i'iometimos it is desirable to do spacing without opcratin a key-lever,as when an error in setting; the carriage occurs. For this purpose llhave the lever 41 apart from the key-levers proper and which is rigidwith shaft 19 thereon. This particular lever has an arm 44, rigid withitself or with shaft 19, adapted to engage push-rod 45, Fig. 5, andthrough arm 23 on rotatable post 13 actuates pawls 14 and 15, thusaffording an independent way for feeding the carriage 5. in thisoperation the moment pawl 14 is disengaged from segment 11-5 the bolt 30is free to act and throw the ham mer-arm 26 forward; but the hammer isdeterred from making a full stroke by the I.- shupcd head 22, which nowserves as a stop by reason of arm 34 striking the top of said headinstead of entering slot 35; but this limitod action of bolt 30 issufficient to rock shaft 27 and pull pawl 1 1 down by means of link 41and arm 12, and thus pick upthe next lower tooth when post 16 is rotatedto its normal position by the pressure of bow-spring 14'.

(in the rear of the carriage 5 are feed-rolls at! and 18, between whichthe sheet of paper printed upon is placed, afecd-spoutdi) for the sheetbeing shown in this machine. The paper is fed upward by these oils withthe inkribbon 51 between it and the type-bar 52. Said bar, Fig. 15,Sheet 4, is adapted to slide back and forth in a slot in the topcross-piece 53 of the main frame to bring any called-for figure intoprinting position. It bearsligurea or characters corrcspomling to thoseon the keyboard, so that the depression of any given key brings thecorresponding character on this bar before hammer 25 for impression.

A line of separate mechanism connects said bar with the key-levers,Figs. 5 and 9. Each i e \,'-lcver 3 has an arm 5 1, projected beyond itspivot on shaft 19, engagim, beneath plate 55, fixed on shaft 56. Thesaid arms are graduated in length according to the denomination or valueof the key-lever in the series, the lever having the highest numeral orcharacter requiring the farthest throw as this machine is organized. Therotation of shaft 56 through wing 55 moves shaft 56 and the miter-gear57 thereon, Fig.1), which meshes with segment 58 on upiight shaft 60.The said shaft 61) has an arm 61 at its upper end, Fig. A, connected bylink 62 with typo-bar 52. This produces exact correspondence andselection between the characters on said bar, which are from U to 9 inthis instance, and

the key-levers of the same value, and the selections are unerring whenthe right lever has been touched. Normally the cipher is opposite hammer25, in which case the bar 52 does not move to make an impression. Spring64, connected with an arm on upright shaft 60, restores said shaftto'initial position after each action.

A separate back-stop is provided to limit the throw of arm 61, accordingto the character selected on the type-bar, said stops consisting ofsmall vertically-movable bolts 66, .each adapted'to shoot up in its own'hole 67, Figs. 2 and 6, when called. These bolts 66 extend from underthe bottom of the machine, Fig. 8, to the top and are operated by thekeylevers through diagonally-arranged levers 68, pivoted between theirends on the under side of the machine and engaged by rods 70 at each toits own key-lever their frdnt ends. These rods are attached and havesprings about them to restore the key-levers to work ing position aftereach depression. The lower ends of said rods simply bear on levers 68,but might be pivoted thereto, and so it occurs when any key-lever isdepressed it throws up its corresponding back-stop bolt for the arm Thismakes positive what might otherwise be an uncertain stop for said bar.Eight of these stops 66 are here shown, one of which, the last one atthe left being a fixed stop. No stop is shown for'the first movement oftype-bar 52,

. because the momentum of the same under the 1 machine and for printing4p in the item to be printed.

"used to engage each its own slight impulse of lever 1 will not carrysaid bar beyond alining position with hammer- 25 to any perceptibledegree.

; .The carriage 5 normally is at the left of the is moved toward theright as many points as there are figures Thus if the sum or item he,say, 365 the carriage is carried over to point the first figure in thehundredscolumn, the second in tens-column, and the third in units, and.the vertical thumb-levers 72, Figs. 5 and 10, particularly serve to fixthe starting place for any given item, large or small. These levers arepivoted in a box- .ing 73 on the front of the carriage and havesubstantially right-angled projections or fingers 74 at their bottomadapted when said levers are particular stop 75 on the frame below, thuspreventing the vmoyingof the carriage to the right farther than theright stop will allow. Thus if the third lever from the right he engagedby the 72- had been operated, sa

thumb to move the carriage to startin '-place in hundreds-columnit wouldengage, say,

.the third lug or stop 75 from the right and stopping the carriage theremake that the starting-point for printing that item, tens being next andunits last. If the wrong lever in. the temthousand column, thespacinglever gz can bemneratedfto bring the machine to set the machineto the right position, and then operations begin through the key-levers.The In gs or stops 75 are staggered, and the points 74 of the levers arearranged in respect thereto so that each will engage only its own stopand none other, and all the levers are arranged to work with thespring-pressed bar 76, or they may have retracting-springs of their own,or both, as preferred, to restore them to normal position. Hence inprinting an item the first thing to do is to bring the carriage to theright place according to the column in which the fix st figure is to beprinted. Then printing goes forward through the key-levers, and thisoperation is repeated for each successive item indefinitely.

The hammer-arm 26, so called, Fig. 8, is really a heavy wire bow havingits two extremities fixed on the shaft 27 at the-sides and bottom of themachine, and the hammer is adjustably secured thereon.

The foregoing mechanism mainly has to do 4 with the printing of items,and the total or sum of the items need not be struck off if not wanted;but it has been faithfully added up as each figure has been recorded andnow nothing remains to be done but to strike off the total in a singleline and at a single stroke by or through the totalizing-hammer. In thiscarrying forward ofthe work for totaliz- 95 ing the items I employasetof adding-wheels 77 and a set of total or recording wheels 78, Figs. 5and 11, and with these the initial operating-wheel 80, through whicheach addingwheel isv reached by sliding wheel in beneath it. There areas many or more addingewheels as key-levers and a certainrecording-wheel geared with each adding-wheel, so that each lever notonly works a line of mechanism to print the items, but also to add theitems as they are printed by carrying their sum forward with the addingand total wheels.

The wheels 77 and 78 are supported within the walls of what is termedthe stationary head 81, Figs. 2 and 9, while wheel 80 is adapted toslide on shaft 82. movement it is controlled by a carrier-arm 83, whichis fixed at its lower end to a longitudinally-sliding shaft or rod 84,Figs. 7 and 9, and this rod is connected by rigid arm with the endlessbelt 12, attached at its top to the carriage 5. The carrier-arm 83engages in the hub of wheel 80, so as to give a positive movement to thewheel and hold .it where adjusted, but leaving the wheel free to turn.Thus it occurs that wheel 80 is caused to respond to every movement ofcarriage 5, and by reason of this connection of arm 83 with belt 12below the drums 10 and 11- the wheel 80 is always moved in the directionopposite to the carriage. Hence if the earriage be moved by hand totheright the said wheel travels a like distance tothe left, and theparts are so arranged relatively that if the carriage be set to startprinting in any In this sliding given column the said wheel will come tothe same column. This also places the said wheel in harmony with, thekey-levers, so that it will carry into the totals the sum called for bysaid levers. If the figure be, say, 5, the wheel will rotate theadding-wheel 7 7 with which it is engaged to carry up five points, andthe same with any one of theseveral addingwheels to which for the timeit may be moved through the keydevers and carriage.

The shaft 82, carrying wheel 80, is rotated from shaft 56, Fig. 5, bysegment 86 thereon engaging segment-gear87 on shaft 82. This gearrotates loosely and carries a pawl 88, which engages ratchet-wheel 89.,fixed on said shaft. Hence this ratchet alwaysholds every point moved upthrough segment 87.

Now referring again to the adding-wheels 77, Fig. 12, it will be noticedthat they are each mounted to rotate on a hub 90, rigid on shaft 91, andeach hub has race and antifriction-balls about its periphery to affordan easy action for said wheels. The hubs 91) are all engaged also withthe parallel rods 92, and each adding-wheel has two cams 93 at its side,with ten points corresponding to ten in addition between the shoulder ofeach cam, and a lever 94 rides on each set of cams through a rollerbearingthereon. Adog95 on each lever 94 engages with ratchet-teeth 96 onthe side of the wheel 77 in the wheel next higher numerically, so thatwhen pivoted lever 94 through its roller jumps or drops off the shoulderof a cam 93 the spring-pressed rod 97 pushes dog 95 forward and gives asingle-point rotation to the next higher adding-wheel, thus carrying anumber into said wheel. The same opera tion extends through all saidwheels, and in this way the items are, first added upintotheadding-wheels themselves. A spring-pressed pawl 98 engages ratchet 96at the side of each wheel to prevent backward rotation.

in order that each higher wheel be unlocked from arm 100 when cam 93 onthe lower adding-wheel shall have reached the point where the carryingforward of a point is necessary, as in recording'when one is added tonine, 1 provide each lever 94 with a side projection or pin, whichin'this instance comprises the extension of the pivot-pin which attachesrod 97 to lever 94. This extension of said pin bears against thevertical arm of dog 100 at a point above its pivot, and whenever cam 93presses lever 94 back said extension releases the next higher wheel bypressing its locking-dog 101) out of engagement with the teeth on saidwheel. The series of higher wheels are all thus released to admit of thecarrying forward of theamounts added to the lower wheels.

Each adding-wheel has also a catch or dog 100, Fig. 11, which isnormally engaged with the teeth thereof to keep the wheel from rotatingexcept when required, and the said catch is substantially L-shaped,pivoted at its angle remote and having its short arm arranged to beengaged and depressed by roller 101 on the top of wheel-carrier 83, sothat when said wheel 80 is slid on its shaft into engagement of any oneof the wheels 77 the roller 101 at the same time unlocks the catch 100.This liberates that particular adding-wheel for rotation, and the catchdrops back as soon as the carrier is moved on. all the catches 100 atthe same time, so as to enable all the adding-wheels to be alike turnedto starting-point after a given task is com plated, 1 provide arotatable cam-shaft 104, Figs. 5 and '11, adapted to bear in the shortarms of catches 109 and throw them all out at once. The said shaft isturned by means of crank-lever 105, Fig. 1, gearlbli on shaft 107, andgear 108 on shaft 1.04. A pawl 110 on the inside of gear 198, Fig. 3,engages it with shaft 104, and thus it is rotated; butsaid pawl can bedisengaged by depressible belt 119. This enables a total to be struckoff at any time without wiping out the additions then in theadding-Wheels, and frequently it is desir" able that this should bedone. Then the gear 108 will run idle, and the other chain of gearsgoing to the paper roll for printing the total and marked 113, 1 i l,115, 116, and 117, succes-r sively, will operate alone, as hereinafterseen.

Referring now to Fig. l, segment 118 on shaft 104 meshes with gear 12-1)on addingwheel shaft 91. way round, which is all it requires to bringthe raiding-wheels back to zero, as a half-rotation of them sullices inany case, havingtwo stopping-points each at their camsl1oulders. Thisalso gives time for the total or aggregate to be struck off through therotation of crank before the adding wheels are set back. in thisrotation of the wheels 77 to more they travel in their usual directionand are each engaged by its own pawl 121 at its side and fixed on one ofthe rods 92, Fig. 12.

The totalizing-lutmurer 123 is fixed on a vibrating frame 122, whichhasa lateral sliding movement suili cient to carry the hammer overopposite the Vital-wheels to strike oil any given total more or less;but it never moves farther over than to take off the total then made.This prevents printing a series of naughts beyond the figures of thetotal, as would occur if the entire nine total-wheels were alwayscovered. 1 limit this action of the hammer to the wheels used by meansof a splined rod 1524, Figs. 5 and 11, adapted to run in a transverseslot across the edge of all the wheels 7 8 and which is open across allof them alike when said wheels are brought back to starting-point.

When this occurs, their ciphers are all alikeexposed at the front. Ofcourse all the wheels not used to print a total remain that way. Hencethe spline-rod 124 can run into all the unused ones; but this is itslimit, and this ,1 utilize to determine the movement of the hammer 123laterally.

When it is desired to disengage (-lear 118 has teeth only halb Fig. 3ready to'be moved to action.

resets g t 1525, her" in -Fig. 1 1 show an inc ing an arm 126 its botgod with s projection on the slid rec 12?, carrying hammer-ironic 1522.At its tor; is an arm 128. connected with one end or the long springpressed spline-rod 11 short arm 136 on shaft 1125, Figs 3 end 6 runs inengagement by roller with cem 131 on shaft 10? in i, 106., and by thusrotating shaft 25 i get I! necessary sweep to both arms 126 end 1528;and they move together the some distance.

Hemmer 123 :ind splined rod 124;; have s. simultaneous lsiterel movementwl ch dependent upon the coiled spring nponfsplined red 12 1 and. com131. The spring normally holds the roller of arm ldongeinst the highpoint of the cam which keeps both hemmer 123 end spline'd rod 124: tothe extreme left until the com is rotated. As the roller rides 0d theshoulder of the com the presses splined rod 124 to the right, whichcerries the spline or key on the rod along the transverse slotheretofore described until the end of the spline strikes against theface of on adding Wheel whicn has been rotated and whose slot in theedge thereof has been moved out of line Hammer 123 moves leterelly'thesome distance es splined rod 1%, end when said rod is stopped so is thehemrncr which. then covers only the adding-wheels upon which the totalis recorded.

The hemmer 123 is caused to strike by shouldered com 133 on short shei't13 5., carrying gear 113, arm 135, lying against said cam, shaft 136,carrying seid arm, and another arm 137., rigid with seid shaft, Fig. 1,and bearing .et its extremity against it boil 138 along the bottom ofhammer-shaft 127. A heavy spring M0 presses against arm 13?, end themoment arm 135 drops 0d the shoulderof cam 130 this spring gives enefiective blow to hammer 123. Normally the seid'sev erel parts are inabout the relation shown in A. depressible stop 1 12 fixes thestopping-point of crank-lever 105, through which these settle-- tionsare made.

In Fig. 4 it will be seen that there are four pins 1 15 in pairs aboveend below the shaft 91., on which rests yielding spriiig erin 1 16,supported on the frame.

The totalizing or total-recording wheels 78 are loosely supported on e.common shaft and have ten characters each on their periphery equallyspaced apart and corresponding teeth at their sides in mesh with theopposite odd: ing-wheeL The two sets of wheels are so arranged thatevery unit added into one is cerried forward into the other set, and theunits, tens, hundreds see, are tar-zen core of in the total-wheelsthrough rotations from the adding-wheels.

Means for actuating the feed-rolls t7 and 18 to set the paper at theproper elevation for each new line of figures to be printed consists .72is ectneted.

/Vhcn the total is to be printed, -the feedrolls are actuated to rotatefirst in one direction to carry the paper down slightly, so that thetotel will be printed in close relation to V the lost figureprinted, andsecond in the 011- posite direction to feed the paper upward efthe totalhas been printed to bring the me in plain view. at the top of themachine. This reverse motion is etteined through gears 113 to 11?, Figs.1 and 3, gear 117 having a. long list-sided shaft which extends intofeedroll shaft 148 to rotate rolls 4:? end slidingly engaged therewithto allow for the side move- 5 merit of the carriage.

In order to obtain a clear and neat print at all times, 1 provideautomatic means actuated by the movement of carriage 5 to constantlychange the inking-surface of the ribbons 51 and170 and which causes theribbons to feed slowly across the face oi the type-bar and type-wheelsfirst in one direction and then in the opposite direction. Diii'erentshades or colors of ribbons are used, so that the items will be printedin one shade and the totals in another. These ribbons are wound ovespools 171, supported at the top and at each side of the frame 2, andpass from one spool to the other across the face of the type-bar and thetype-wheels. 'Spools 171 are splined to vertical shafts 17 2 and causedvto alternately rotate in opposite directions when the ribbon is unwoundentirely upon either of the spoolsr The vertical shafts 172 areslidingly mounted in arms on the frame 2 and have each a pin 173.adapted to engage a notched sleeve or collar 174, rotatably held in arm175. This collar has a beveled gear 176 meshing with beveled gear 177.on cross-shaft 178. This shaft has a larger beveled gear 17 9 meshingwith a gear 180, that is actuated through suitable gearing fromspring-tension carriageopcrating shaft 9. Only one of the pins 173 is inengagement with a notched sleeve 174; at a time, and it is byreleasingand relocking these sleeves for each shaft 175?, that the said shaftsare made to reverse' This is accomplished by means of the cross-rod190., having the arms extending at opposite sides of the center at theends and which engage the lower extremities of the vertical shafts 172and be in]; in constant touch therewith. "On each shaft 172 are thegears 181, which mesh and have a sliding movement with gears 182 on thevertical screw-threaded shaft 183, mounted to. rotate in the frame atthe side oi shait 172. A nut 184 on each shaft 17 2 has an extensionwhich bears at certain intervals upon a spring 185, resting on a collaron said shafts. As shaft 17 22 rotates screw-tlueaded shaft 183 is alsorotated and causes the nut to travel up or'down. As shown. the hut 18stat the right side of the machine is caused to travel down while the nutat the left goes up ward. The nut coming down engages spring; 185 andgradually compresses it, and it nothing' were to hold the shaft 17 2- inraised position pin 173 would drop into notched sleeve 175. This ispermitted only when the ribbon on spool 171 at that end of the machinehas been unwound and reached the end of its travel where fastened to thesaid spool. Each spool is provided with apivoted catch 187 having: aspring to press the free and outward, and also having a separatespring-pressed bolt 18h, which rests in the groove 189 near the top ofshaft l72-that is to say, in that particular shaft which istci'nporarily to beheld in raised position. The ribbon 170 bears againstthe free end of catch 187 and normally holds the same bach reacts andits bolt its. in locking engagement until the ribbon has entirelyunwouml itself. This trees the catch, and its spring; forces it outwardand withdraws the bolt from groove 189, allowing spring 185 to pressshaft 172 down and lock pin 173 with sleeve 175. The lower extremity ofshaft 17 2 lorcesdown the arm on cross-rod 190 and rocks thissuilicicntly to cause .the arm at the other end to force shaft 17 2 atthe left up, thus freeing its locking-pin connection with sleeve 17 5 atthat side. As this shaft 172 is raised it is held in that position bybolt 188, entering shaft-groove 189, until the ribbon at that side isunwound these movements being automatically controlled at each side ofthe machine and the ribbons being fed in reverse direction at longintervals.

Now as an example in operation suppose that two items---- 852 i and598--'are to be printed and added together, in which the total is 14:22.Having" set the machine to start printing in the third. or hundredscolumn and striking the hey-lever 8 for the lirst item, an imprint oisaid figure will be taken from the type-bar in the item-line, and thehundreds-adding wheel will be turned up eight points with acorresponding movement of the opposite totaliain ewheel. Then havingprinted the figures it and 4: of this item in their columns there willbe 824; represented in both the adding-Wheels and the totalwheels-t,which latter are an expression of the value in the adding-wheels andalso an imprint of 89st on the paper from the typebar. Then afterrecording the next item, 598, in like manner and really having M22 inthese wheels the hundreds-wheel necessarily is carried three points pastthe ten therein, and one point is turned forward in the thousands-wheelat its left. The fur ther addition increases the totals in all threewheel-columns and carries forward another hundred in the hundredscolumn.it has also occurred in the units'colnmn that one ton has been taken outand carried forward in the tens-column, leaving two therein, while onetea has been taken out of the tcnacolumn and carried forward into thehundreds, leaving two therein. New referring to the totalizing-- wheelsit will be found that they have been rotated to correspond exactly tothe results in the addingevhcels and that when the total is struchtherefrom it will show up w 1422.,

' the sum of both items,

The recording-wheels are so called by ititt' son of their serving togive the record in print, and their mines are always the same as thoseoi the addhnrerheels which they represent.
